I had one that did until they figured out how to make an account. They go away. Its usually a reaction to posting information they don't like, or questioning such information. But I just post info, questions, and statements. HMF makes final calls. The replier can simply argue in public, but they don't because its vitriol. So I ignore it so it goes away, because I don't want to trash the site up. Roses are for peace, serenity, tranquility, amusement, bewilderment, and other such similar rare, abstract states of existence. HMF is also a resource for helping, as well stringing the historical record of roses together (and sometimes finding the lost fragments). So I simply don't feed the trolls. If not feeding them does not work, then I would definitely report them.
